Petunia would face the challenge of raising Harry in a world she despises. She has always been envious and resentful of Lily's magical abilities. Now she has to raise a magical child. She would also have to deal with the social stigma in the Muggle world. People might think Harry is strange because of his odd behavior due to his magic. And she would constantly worry about Harry getting into trouble in the wizarding world that she doesn't understand.
Well, it could be really interesting. Petunia has always been resentful of magic in the original story. But if she raises Harry alone, she might gradually come to understand the magic world. Maybe she'd start to see the good in Harry's abilities and protect him not just out of obligation but out of a new - found love. For example, she could secretly learn about magic to help Harry with his school work or protect him from the dark forces that lurk in the wizarding world.
I don't think it's a very common type. Most 'Harry Potter' fanfics tend to focus on the magical adventures, the relationships between the main characters like Harry, Ron and Hermione, or exploring different magical elements in the wizarding world. While there are some that might delve into darker themes, the idea of Petunia abusing Harry isn't as mainstream as other topics in the fanfic community.
By focusing on their shared past traumas. For example, both have had experiences related to Lily's death in different ways. Harry lost his mother, and Petunia lost her sister. They could start to bond over this common pain and gradually move towards a more positive relationship.
Definitely. Fanfic writers often explore Petunia's role in Harry's life in a more positive light. Maybe she had some internal struggles about taking Harry in, not just out of spite but also out of fear of the wizarding world. Such fanfics can offer new insights into the 'Harry Potter' universe and its characters.
One possible fanfic could be about Petunia Dursley finding a magical toy that once belonged to Harry Potter's parents. Maybe she discovers it in the attic and it starts to show her memories of Lily and James Potter. She realizes that she has been wrong about Harry all along and decides to change her attitude towards him.
Another challenge would be his changed appearance. His fangs and pale complexion could make it difficult for him to blend in at Hogwarts. He might be ostracized by some students and even some teachers. His vampiric abilities, while useful in some ways, could also be a hindrance as he tries to maintain his normal wizard life. For instance, his sensitivity to sunlight could limit his outdoor activities during the day.
In a fanfic, Harry as a girl would face the challenge of re - defining her identity. She has been known as a male hero, and now she has to create a new image for herself. This could be difficult in the wizarding community where reputations are important. She would also have to adapt to the physical differences, like having a different body structure for dueling or flying on a broomstick, which could take time to get used to.
One challenge would be the goblins. They are very protective of Gringotts and would not easily give up control. They have their own laws and traditions regarding ownership. Harry would have to deal with their resistance and find a way to convince them or negotiate with them.
One great Petunia fanfiction could be one where she has a moment of self - realization. Maybe she discovers some of Lily's old magic things and starts to understand the wizarding world better. It could show her in a more sympathetic light, perhaps she even tries to protect Harry in her own way.
Maintaining the balance between the different houses is always a struggle. There might be rivalries that get out of hand, or a sense of unfairness among students regarding house points and privileges. The headmaster would need to find ways to promote unity and a healthy competitive spirit.
